IMPROVEMENT IN CARCOUPLINGS.

Specification forming part of Letters Patent No. 175,690, dated April 4,1876; application filed November 22, 1875.

To all whom it may concern:

Be it known that we, DAVID T. GILLIAM and CHARLES F. GILLIAM, of Nelsonville, county ot' Athens, and State of Ohio, have invented a new anduseful Improvement in Oar- Oouplin g, which improvement is fully setforth in the following specification, reference being had to theaccompanying drawings.

The object of our invention is to form a self car-coupler, whichcan bemanipulated without danger or inconvenience by persons on the car.

Figure 3 shows a sectional side View of the coupler as it appears whencoupled.

The coupler consists of a draw-head, A, Fig. 3, and coupling-bar, Fig.2. The drawhead A, Fig. 3, differs from those in common use in that ithas a more haring mouth, and

Iis countersunk in the top to accommodate the eled from the catch O tothe end, in order to give additional breadth to the mouth of thedraw-head.

Fig. 2shows thc coupling-bar. It is provided with acatch, C', at eitherend, upper side, to interlock with catch O, Fig. 3, ot'draW-.hearh andis beveled on all four sides from catch outward.

Fig. l shows the eXtra link. The catch C is to interlock with O of Fig.3, While the other end has no catch, but is provided with al1 opening,H, to apply to link-and-pin couplers in common use.

The couplingbar being fixed in one of the draw-heads, all that isnecessary to effect a coupling is, that it collide'with anotherdrawhead, when, by the special arrangement ofthe flaring mouth ofthedraw-head and the tapering end ofthe coupling-bar, it is directed underthe drop-latch, and coupling is effected.

We claim- The combination ofdraw-head, having countersunk or open-topdrop-latch B, pivoted at E, and provided With shoulder D and handie F,and coupling-bar, having catches O C', I

all substantially as specified.

In testimony that we claim the foregoing as our own we aix oursignatures in presence of two witnesses.

DAVID T. GILLIAM. y CHARLES E. GILLIAM.
